                         POINT(S) OF RECEIPT


                    SERVICE AGREEMENT (CONTINUED)

         Buyer shall  deliver or cause to be  delivered  gas at the  point(s) of
receipt  hereunder at a pressure  sufficient to allow the gas to enter  Seller=s

delivered  by Buyer  shall not  exceed  the  maximum  operating  pressure(s)  of
Seller=s  pipeline system at such point(s) of receipt.  In the event the maximum
operating  pressure(s) of Seller=s  pipeline system,  at the point(s) of receipt
hereunder,  is from  time to time  increased  or  decreased,  then  the  maximum
allowable pressure(s) of the gas delivered or caused to be delivered by Buyer to
Seller  at the  point(s)  of  receipt  shall  be  correspondingly  increased  or
decreased upon written  notification of Seller to Buyer. The point(s) of receipt

adequate  security  in  accordance  with  Section  32 of the  General  Terms and
Conditions of Seller's Volume No. 1 Tariff. As set forth in Section 8 of Article

2/       Transco's  ability to receive gas under this Rate  Schedule at specific
         point(s) of receipt is subject to the operating  limitations of Transco
         and the  upstream  party  at such  point(s)  and  the  availability  of
         capacity at such point(s) of receipt.

3/       These  quantities  do not include  the  additional  quantities  of gas
         retained by Seller for  applicable compressor fuel and line loss
         make-up  provided for in Article V, 2 of this Service  Agreement,
         which are subject to change as provided for in Article V, 2 hereof.
         The volume  provided  for each tier  represents the maximum  allowable

         cumulative  capacity  entitlement  for all receipt points provided
         herein shall not exceed the specified  capacity  entitlement  provided
         for Tier III, which amount  shall equal  Shipper's  transportation
         contract  demand  quantity.  To the extent that on any day other
         participants  in  Transco's  Southern  Expansion  Project are not
         utilizing  their total daily TCQ within a Tier,  Transco is willing to
         receive  additional  quantities  of gas from  Shipper at such points
         within such Tier, on an interruptible basis, not to exceed Shipper's
         total daily TCQ.
